dominating blow

So i'm playing a marauder, with Facebreaker. Using dominating blow + melee splash support + melee physical damage support + multistrike support. I was also using shield charge, but I find myself just walking into groups of mobs now and just kill/charming them. Any suggestions on what I could replace shield charge with? I'm also using, ancestral warchief, summon ice golem, and Hatred.
